JS library for processing and procedural image generation?

Question

JavaScript

The library requires not so much a set of standard actions on images (blur, grayscale ..), but rather the generation of a normal map, scratches, bricks and other things.
JIMP does not know how to do this (and weighs quite a lot). Moreover, separately libraries for generating normal maps, scratches could not be found. Is there a suitable one?

Answer 1

It was never possible to find a suitable one, especially since the requirements increased (as regards performance).
I prepared the debut version of my texturity.js library , which draws through WebGL (which is incomparable to the usual Canvas) and works in the same context, which allows you to draw on different instances without any delayTexturity.Canvas
